Today, persons with a visual impairment use a cane to explore their surroundings and sense objects in their vicinity. While electronic aids have been proposed to aid them, they communicate limited information or require a fixed position. We propose VibroVision, a vest that projects information about the area in front of the wearer onto her abdomen in the form of a two-dimensional tactile image rendered by an array of vibration motors. This vest enables the user to sense features such as shape, position, and distance of objects in front of her.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
